With camera offences - speed camera, traffic light camera - the law is quite clear. A Notice of Intended Prosecution must be sent out to the Registered Keeper in time to reach the addressee within 14 days.
Would the same thing apply here? I'm assuming he wasn't spoken to by the police at the time (I didn't see the programme) but it is an interesting point of law if the tv programme was broadcast after the 14 days or even within that time period.
You've given me something to think about.
